Cysic’s CYS token surged before South Korean exchange Upbit announced new BTC and USDT trading pairs on Aug. 10, drawing attention to the timing of one of the token’s largest intraday moves. 

Upbit initially scheduled trading for 14:00 KST, but the exchange has since postponed the opening twice, with its latest notice moving the launch to 20:00 KST.

That update is important because CYS had already recorded much of its price surge before Upbit trading began. At the time of research, the new markets had not yet opened, meaning the rally cannot be described as buying activity occurring on Upbit itself.

Cysic rally came before Upbit announced the listing

Upbit published its original CYS trading announcement on Aug. 10, saying it would add CYS/BTC and CYS/USDT markets and support deposits and withdrawals through Base. The exchange initially targeted 14:00 KST for trading. Its official social media post confirms that original schedule.

The timing of CYS’s price action came earlier. CYS climbed from around $0.80 to a wick near $1.30, with the largest move occurring around 23:00 UTC on Aug. 9. Upbit’s public listing announcement arrived several hours later.

That sequence has prompted unverified speculation online about whether some traders had advance knowledge of the listing. However, there is currently no verified evidence establishing that Upbit information leaked or that insider trading occurred. Neither the price chart nor the timing alone proves misconduct, and no official investigation or finding reviewed for this story supports such a conclusion.

CYS was also rallying before the Upbit news. CoinGecko historical data show the token closing around $0.54 on Aug. 4, $0.83 on Aug. 5 and $0.95 on Aug. 7, demonstrating that its broader advance had already been underway for several sessions.

Upbit delays Cysic trading twice to 20:00 KST

The exchange changed the timetable shortly after announcing the six new assets. Upbit first moved trading for CYS, ICNT, XAN, EDEN, AIOZ and ALLO from 14:00 KST to 17:00 KST. Its official post identified the revised opening time directly.

A second update at 16:45 KST then pushed the launch from 17:00 KST to 20:00 KST. Upbit’s official Telegram channel recorded the additional schedule change after its earlier postponement. The exchange’s notice did not attribute either delay to a problem with CYS specifically.

Upbit had warned in the original announcement that trading could be delayed if sufficient liquidity was not secured after deposits and withdrawals opened. Similar provisions have appeared in other listings. As crypto.news reported in recent CAP listing coverage, new Upbit markets can be postponed when opening liquidity does not meet the exchange’s requirements.

Once CYS trading begins, Upbit plans to restrict buy orders for approximately five minutes. Sell orders priced more than 10% below the previous day’s reference close will face a similar initial restriction, while only limit orders will be accepted for roughly the first two hours.

Cysic price data show a volatile record attempt

CYS was trading near $0.92 at the latest CoinGecko reading, up about 11% over 24 hours and more than 223% over seven days. Its market capitalization was around $150 million, based on roughly 160 million circulating tokens. Twenty four hour volume stood above $70 million.

CoinGecko currently lists Cysic’s all time high at $1.28. The safest interpretation is that CYS reached a new record on some trading venues, while the exact peak depends on the exchange and price feed used.

The volatility is not unusual around major South Korean exchange announcements. In recent GRVT listing coverage, GRVT had already risen 23% before its scheduled Upbit opening. Likewise, earlier CFX listing coverage showed Conflux gaining about 8.5% before trading began. Neither case proves the announcement was the sole cause of the preceding price move.

What happens next when Upbit opens Cysic markets

The immediate event is the scheduled 20:00 KST opening of CYS/BTC and CYS/USDT trading. Traders will then be able to distinguish the pre listing price move from the actual market response once Upbit orders begin executing.

Cysic describes itself as a decentralized compute network connecting hardware capacity with demand for zero knowledge and AI computation. Its official documentation says participants can provide compute resources and earn CYS, while the network supports workloads ranging from consumer hardware to GPUs and specialized ZK equipment.

South Korea remains an important market for exchange driven altcoin activity despite weaker overall volumes. As crypto.news reported in South Korean trading data, Upbit accounted for 67.4% of trading among the country’s five major won based exchanges during the measured July period.

For CYS, the next test is therefore the market opening itself. The token has already experienced a sharp rally and retracement before Upbit trading started. Whether the new BTC and USDT pairs create sustained demand will only become measurable after trading begins.

A Bitcoin security researcher says he lost access to OpenAI’s Trust & Cyber tooling while working on ongoing red-team scans, forcing him to revert to alternative AI options for future analysis. The episode underscores a broader worry shared by parts of the crypto defense community: that the most capable AI systems may not be readily available to those trying to harden public code against cyber threats.

In an X post on Tuesday, AnchorWatch CEO Rob Hamilton said he began integrating OpenAI’s Trust & Cyber capabilities into his Bitcoin Red Team efforts on Saturday. He later reported that his access was restricted the following morning, prompting him to switch back to using Chinese open-source models for vulnerability research. Hamilton framed the change as a practical necessity for maintaining defensive work rather than a preferred approach.

Key takeaways

• Hamilton says access to OpenAI’s Trust & Cyber capabilities was restricted after he started using it for Bitcoin Red Team research.
• He plans to continue scanning Bitcoin-related repositories using Chinese open-source AI models rather than relying on the previously integrated tooling.
• Bitcoin Red Team’s approach combines AI-assisted scanning with human review across hundreds of open-source repositories.
• The incident echoes wider concerns from crypto leaders that “frontier” AI access remains limited despite rising cyber risk.

A sudden access restriction changes the research workflow

Hamilton’s post describes a short integration window: after beginning to use OpenAI’s Trust & Cyber tools for Bitcoin Red Team on Saturday, he said he was prevented from continuing the investigation after access was restricted the next day. In his view, the restriction limited not only the ability to evaluate existing code changes but also to check whether additional issues remained undiscovered.

Hamilton also characterized the situation as a policy bottleneck, implying that defensive teams are constrained by rules that attackers can bypass. He argued that “intelligence is unrestricted” for actors who pursue harm, while defenders conducting “harm reduction” are left without comparable tooling. The core point is less about the specific model choice and more about continuity: red-team work depends on sustained access to iterative analysis tools as scans evolve and new leads emerge.

Why this matters for Bitcoin security testing

Bitcoin Red Team is described as a volunteer effort using AI tools and human review to examine a large number of Bitcoin-related open-source repositories for vulnerabilities. According to the account referenced in Hamilton’s post, the work has been particularly active in the wake of major wallet security incidents.

That timing is important because defenders often need rapid, repeatable workflows to assess code changes across a sprawling ecosystem. When an AI tool is removed midstream, it can slow down verification, increase manual effort, or force researchers to restart parts of their process with different systems. Hamilton’s statement suggests the restriction wasn’t merely a temporary inconvenience—it affected his ability to continue investigating code updates and to explore whether other weaknesses might be present.

His comment also reflects a recurring pattern in security research: tools that speed up initial discovery are only as useful as the ability to keep investigating after early findings. If the process is cut short, the risk of leaving unresolved vulnerabilities rises, especially in open-source environments where issues may be subtle and scattered across multiple repositories.

Escalating threat pressure and limited AI access

The episode fits into a larger debate inside crypto about who gets access to advanced AI capabilities. Earlier coverage referenced in the article notes that crypto executives told Cointelegraph last month that many major firms were still waiting to obtain powerful new AI models to help secure their code against escalating cyber threats, with only a select few having been able to get access.

Bringing Hamilton’s account into that context, the risk for the broader sector is not only that attackers will improve their methods, but that defenders may not be able to match speed and depth. If the most effective tools are restricted, available only to a narrow set of organizations, or subject to sudden changes in access policy, the defense pipeline may become uneven.

Hamilton’s complaint is also notable for its emphasis on “sufficient” code changes. In vulnerability research, it is not enough to identify a potential bug; teams also need to confirm that patches address the underlying issue and do not introduce new problems. Cutting off access at the point where verification is needed is therefore more damaging than removing a tool at the early scanning stage.

What readers should watch next

The immediate story is a researcher switching back to Chinese open-source AI models after reporting restricted access to OpenAI’s Trust & Cyber capabilities. Going forward, observers will likely focus on whether Bitcoin Red Team can maintain its scan velocity and depth without the previously used tools, and whether other crypto security teams report similar access volatility as they try to use frontier AI for defensive purposes.

“They came to us highly recommended by an alumni CEO that we had already backed,” Rist told CoinDesk in an interview. “So, there was a lot of trust there, and this CEO said, ‘You got to meet these guys’. They were serial entrepreneurs coming out of South Africa. They’d never built businesses outside of South Africa, but they were hungry. They were relentless.”

Despite enjoying a sturdy exit, Rist said he feels mixed emotions toward the Mastercard acquisition, having been part of the whole BVNK journey. “It’s actually sad to sign the papers, almost like sending your son off to boarding school,” he said.

Chris Harmse, co-founder and chief business officer at BVNK echoed this: “It’s been an incredible journey,” he said in an email. “Concentric has been a valued partner throughout that journey.”

Stablecoins, one of the busiest areas of crypto, have become a focal point for the large card networks and payments players. The total stablecoin market cap is about $300 billion, according to CoinGecko data.

The proverbial cat was set loose among the pigeons when Stripe acquired stablecoin infrastructure firm Bridge in late 2024 for $1.1 billion. This probably put pressure on the likes of Visa and Mastercard to start kicking the tires of other stablecoin shops so as not to be outflanked by Stripe’s aggressive approach.

Robinhood has begun offering cryptocurrency trading to eligible UK customers, giving users access to more than 50 digital assets through Bitstamp inside its main investing app.

According to a Bloomberg report, the rollout starts this week and brings crypto trading alongside Robinhood’s existing UK products, which include equities, stocks and shares ISAs, options and futures.

Customers can buy and sell assets including Bitcoin, Ethereum, XRP and HYPE, with the trades handled by Bitstamp UK Ltd. Robinhood acquired the long-running crypto exchange for $200 million last year and has since used the business to support parts of its international crypto expansion.

The UK service carries no trading, custody or account maintenance fees, Robinhood said. Customers will instead pay a 0.1% foreign exchange fee when converting currencies, while certain conversions made during weekends will carry a 0.3% fee.

Robinhood crypto trading starts after FCA registration

The launch follows regulatory approval secured shortly before the product rollout. Robinhood’s UK subsidiary was added to the Financial Conduct Authority’s register of cryptoasset firms on July 31, clearing a regulatory requirement for providing cryptocurrency services in the country.

Under the existing UK system, crypto firms must register with the FCA and comply with anti-money laundering requirements before offering covered services. Robinhood had previously disclosed during its July 29 second-quarter earnings report that it planned to introduce crypto products in the UK but did not provide a launch date at the time.

Crypto trading is being provided through Bitstamp UK Ltd, which is registered with the FCA as a cryptoasset service provider. Robinhood warned that cryptocurrencies held through Bitstamp UK are not protected by the Financial Services Compensation Scheme or covered by the Financial Ombudsman Service.

Jordan Sinclair, president of Robinhood UK Ltd and general manager of Bitstamp UK Ltd, said the company sees digital assets becoming an important part of investment portfolios among a new group of UK investors.

“With today’s launch, we’re taking another major step toward becoming the all-in-one investment platform for the UK,” Sinclair said.

Robinhood enters the market before another regulatory change scheduled for the UK crypto sector. Applications under the country’s incoming crypto authorization framework are expected to open at the end of September and remain available until the end of February 2027, with the full regime scheduled to take effect in October 2027.

The FCA registration obtained under the current anti-money laundering framework does not replace authorization under the incoming system. Companies seeking to continue providing covered crypto services after the transition will need to meet the requirements of the new regime.

Cortex adds AI analysis to Robinhood’s UK crypto service

Alongside trading, Robinhood is introducing Cortex Digests for Crypto to UK customers as part of the rollout.

The generative AI feature processes breaking news, technical indicators, market information and Robinhood’s proprietary data to provide explanations for price movements in individual cryptocurrencies. According to the company, the tool is designed to give investors additional market context when evaluating digital assets.

Adding the feature extends Robinhood Cortex into a crypto service that now sits inside the same application as the company’s other UK investment products.

The launch also connects UK customers to a crypto business that has expanded beyond buying and selling tokens. Robinhood has been developing its own blockchain infrastructure through Robinhood Chain, a permissionless Layer 2 network built using Arbitrum technology.

According to company figures, Robinhood Chain has recorded more than $18 billion in decentralized exchange trading volume and more than $840 million in total value locked since launching on July 1.

Developers worldwide, including those in the UK, can build applications on the network. Robinhood has described the blockchain as infrastructure developed to institutional standards.

During the company’s latest earnings period, CEO Vlad Tenev said Robinhood Chain had become the fastest Ethereum Virtual Machine-compatible blockchain to reach 100 million transactions.

Crypto revenue fell as Robinhood expanded other businesses

The UK rollout comes after Robinhood reported lower cryptocurrency transaction revenue during the second quarter despite expanding its digital asset products.

Crypto transaction revenue fell 38% from a year earlier to $100 million in the quarter ended June 30, according to financial results released on July 29.

Other parts of Robinhood’s trading business recorded stronger growth. Prediction markets generated $156 million during the quarter, exceeding crypto transaction revenue for the first time.

Total net revenue increased 32% year over year to $1.31 billion, while net income rose 48% to $573 million compared with the second quarter of 2025.

During the same period, Robinhood launched Robinhood Chain, expanded its Stock Tokens product to more than 120 countries, introduced Robinhood Earn and completed its acquisition of Canadian crypto platform WonderFi.

Prediction markets have also become a larger part of the company’s product lineup. The Wall Street Journal reported in July that Robinhood had discussed adding event contracts from Crypto.com to its prediction markets hub, although neither company confirmed an agreement.

Robinhood already distributes contracts through Kalshi and ForecastEx, while it also operates Rothera through a joint venture with Susquehanna International Group.

Robinhood has continued adding products outside crypto

Days before launching UK crypto trading, Robinhood also filed to raise as much as $200 million for its second publicly listed venture fund.

Regulatory filings showed Robinhood Ventures Fund II plans to offer 7.6 million shares at $25 each, with Robinhood separately selling another 400,000 shares. Subject to regulatory approval, the fund is expected to begin trading on the New York Stock Exchange under the ticker RVII on Aug. 13.

Unlike Robinhood Ventures Fund I, which concentrated on later-stage private companies including OpenAI, Stripe, SpaceX and Databricks, RVII is structured mainly around earlier-stage businesses.

The fund is expected to begin with investments in about 80 private companies and will primarily target seed-stage businesses connected to Y Combinator, including companies founded by current or former accelerator participants and YC alumni.

Robinhood Ventures head Sarah Pinto said the structure is intended to give retail investors access to companies earlier in their development rather than requiring them to wait until an initial public offering.

RVII also introduces fees that were not part of Robinhood’s first venture fund. Regulatory disclosures show investors will pay a 2% annual management fee and a 20% incentive fee on realized gains, while the prospectus warns that shareholders will not have redemption rights before liquidation.

The subscription period is scheduled to close on Aug. 12, according to the filing, with Goldman Sachs serving as lead bookrunner and Citigroup, JPMorgan, UBS and Wells Fargo acting as joint bookrunners.

UMX, the Unified Market Exchange incubated by Li Lin’s Avenir Group, launched an invitation only public beta on Aug. 10 for professional investors. 

The platform combines crypto trading with access to real U.S. stocks, ETFs and U.S. stock options, according to a PANews report citing official disclosures.

The beta is built around moving capital between crypto and securities accounts rather than keeping the two markets separate. UMX says eligible users can trade crypto spot, margin, contracts and options while also accessing U.S. securities through the same broader platform.

UMX beta combines crypto and real U.S. securities

UMX says its securities service gives users positions in actual U.S. shares rather than CFDs or products that only track stock prices. A Wu Blockchain review of UMX disclosures says the service includes stocks, ETFs, options and fractional shares, with trading spanning premarket, regular, after hours and overnight sessions.

The platform is aimed at global professional investors, but access depends on location, account status and product eligibility. The launch material does not establish that the securities service is available to U.S. residents. Offering U.S. listed assets and serving customers located in the U.S. are separate questions, so the distinction should remain clear until UMX publishes more jurisdiction specific details.

Cross asset tools connect stablecoins, crypto and shares

UMX’s main feature is the capital bridge between its crypto and securities sides. Through “Exchange Transfer,” users can convert stablecoins such as USDT into U.S. dollars and move the funds into a securities account. “Loan Transfer” allows crypto assets other than stablecoins to serve as collateral for purchasing power used to trade stocks, ETFs and U.S. stock options.

The platform also says securities holdings can be converted through a “Shares to Token” function into corresponding stock tokens. Those tokens can count toward crypto account margin at applicable discount rates and can later be converted back into securities. The launch reports reviewed do not identify the blockchain, token issuer or detailed custody structure behind those converted positions.

UMX is also testing cross asset margin treatment for eligible wealth management balances. During the beta, it advertises maximum annualized yields of “up to 2.5%” for BTC and “up to 5.5%” for USDT products. Those figures are platform advertised rates rather than guaranteed returns, and UMX says rates, limits and terms depend on the individual product.

Avenir brings a large Bitcoin ETF position to UMX

Avenir Group describes its strategy as integrating traditional finance and digital assets through investment, incubation and operations. The firm has also invested in trading infrastructure, including a February partnership with CoinRoutes aimed at improving institutional execution and capital efficiency across fragmented markets.

An SEC filing by Avenir Tech Ltd, signed by Li Lin, shows 18,276,100 BlackRock iShares Bitcoin Trust shares worth about $702.2 million as of March 31. The filing was submitted May 15 and remains the latest quarterly 13F available as of Aug. 10.

As crypto.news reported in earlier Avenir coverage, the group had already built a large regulated Bitcoin ETF position before expanding further into infrastructure connecting traditional and digital finance.

UMX also enters a market where crypto platforms are moving toward broader financial services. In Binance’s stock trading rollout, eligible users outside the U.S. gained access to thousands of U.S. stocks and ETFs. Meanwhile, recent NYSE tokenization coverage shows traditional exchanges pursuing blockchain based securities infrastructure from the opposite direction.

What happens next for UMX

The public beta remains invitation only. Users with a beta code can register, while those without one can reserve access to the full version and receive launch notifications. UMX has not disclosed a firm date for its wider release in the launch material reviewed.

The next details to watch are the legal entities providing each securities and crypto service, jurisdiction restrictions, custody arrangements and the mechanics behind stock token conversions. For now, the confirmed development is the beta itself: UMX is testing a framework designed to make stablecoins, crypto collateral and real U.S. securities usable within a shared capital system.

A Bitcoin security researcher says he lost access to an OpenAI capability used in his ongoing vulnerability reviews, forcing him to shift back to open-source Chinese AI models. The move underscores a broader concern within parts of the crypto security community: that the most advanced AI systems may be difficult for “defenders” to use, even when the intent is to reduce risk.

In a post on X Tuesday, AnchorWatch CEO Rob Hamilton said he began integrating OpenAI’s Trust & Cyber capabilities into his Bitcoin Red Team effort on Saturday, only to find his access restricted the next morning. “It absolutely guts me as a patriotic American to have to do this,” Hamilton wrote, adding that he would return to using Chinese open-source models to continue protecting Bitcoin infrastructure.

Key takeaways

• Rob Hamilton says access to OpenAI’s Trust & Cyber was restricted shortly after he began integrating it into Bitcoin Red Team work.
• Hamilton frames the change as a defensive tradeoff: open AI models are accessible, while certain frontier tools may be harder for defenders to retain.
• Bitcoin Red Team conducts vulnerability scanning across hundreds of open-source Bitcoin-related repositories using a mix of AI assistance and human review.
• Recent hacks in the hardware wallet space have increased pressure on teams trying to detect issues earlier in the development lifecycle.

How Bitcoin Red Team is using AI to find vulnerabilities

Bitcoin Red Team is a volunteer effort that scans a large set of open-source Bitcoin-related repositories for potential vulnerabilities. According to Hamilton’s account, the work relies on AI tools combined with human verification, with the goal of identifying weaknesses that may otherwise go unnoticed or be discovered only after exploitation.

The group’s efforts have reportedly intensified following a widely discussed incident involving a Coldcard hardware wallet hack, which earlier reporting described as resulting in more than $100 million in stolen Bitcoin. While Hamilton’s post does not quantify how the OpenAI access affected the rate or quality of findings, it does connect the research workflow to a broader urgency—namely, that attackers are actively searching for flaws in the systems people rely on to keep funds secure.

What Hamilton says changed after integrating OpenAI Trust & Cyber

Hamilton’s explanation is straightforward: he started using OpenAI’s Trust & Cyber capabilities to support his team’s review process, then lost the ability to continue the investigation that same week. He said he was “prevented from being able to continue the investigation in a further effort to make sure their code changes are sufficient” and also to determine whether other issues remained undiscovered.

In a follow-up argument about the incentive structure for AI access, Hamilton suggested there is a “local minima in policy,” implying that rules governing the availability of intelligence-focused AI capabilities may unintentionally narrow who can use them for defensive purposes. He added that while “black hats” would not hit these issues, “white hats” could be left on the sidelines if the tooling is restricted.

Hamilton’s characterization is notable because it positions the problem less as a technical limitation of AI and more as an access and policy constraint affecting security research workflows. For investors, users, and builders, the practical concern is that fewer defender teams may be able to run high-end analysis at scale—at the exact moment when vulnerabilities across crypto infrastructure need faster detection.

Broader friction over “frontier” AI access in crypto security

This complaint fits into a pattern that has already been raised by crypto executives. Earlier coverage from Cointelegraph noted that many of crypto’s largest players were “still waiting to gain access” to powerful new AI models to strengthen their code from attacks, with only a limited number able to obtain it. In that context, Hamilton’s experience appears as a micro-level example of how access can be uneven—even for teams working on vulnerability discovery rather than exploitation.

The tension is that crypto ecosystems can’t rely solely on open-source tooling if the industry’s risk profile increasingly demands rapid review of complex codebases. Yet, if leading AI providers constrain usage in ways that make defensive experimentation difficult to sustain, security efforts may end up dependent on a patchwork of what is available rather than what is best suited for the task.

Why the shift back to open-source models matters

Hamilton said he would return to Chinese open-source models after the access restriction. That change is significant for two reasons.

• Continuity: If defender access to frontier systems is inconsistent, researchers may need fallback approaches they can run without interruptions. Open-source models can be deployed and iterated on without waiting for new permissions.
• Coverage and speed: Teams scanning “hundreds” of repositories depend on automated support to review large volumes. If access to an advanced tool is removed midstream, the research cadence and scope can be affected unless an alternative system fills the gap quickly.

At the same time, Hamilton’s stance does not necessarily imply that open-source models are always inferior. Instead, his argument is that defensive research is being forced to operate within the boundaries of whatever AI is available—while attackers face fewer barriers to pursuing harmful goals. That framing raises a question for the community: how can security research leverage advanced AI while still operating under restrictions intended to prevent misuse?

For readers tracking crypto risk, this story is less about who “has” cutting-edge AI at any given moment and more about whether defender capability can be maintained over time. The next inflection point will be whether access policies are clarified, expanded, or made more predictable for security-focused use cases—especially as vulnerabilities continue to be discovered across wallets and other critical infrastructure.

Hamilton’s update leaves one key uncertainty: what specifically triggered the restriction and whether it was temporary or permanent. What readers should watch next is whether other security teams report similar access changes, and how quickly research workflows adapt without losing the ability to uncover vulnerabilities before they reach production.
